Hi, I'm trying to save some additional data to chunks, and have figured out that Capabilities are probably the way to go. After looking around the internet for a bit I think I got the gist and I set to coding. However, the AttachCapabilitiesEvent#addCapability() method seems to require an ICapabilityProvider, which I don't remember seeing anything on. Here's what I've got so far:

 

IRift class:

public interface IRift {
	boolean isRift();
	float getRiftActivityPercent();
	void setRiftActivityPercent(float riftActivityPercent);
	void makeRift();
	void closeRift();
	void riftEvent();
}

 

RiftStorage class:

public class RiftStorage implements Capability.IStorage<IRift> {

	@Override
	public INBT writeNBT(Capability<IRift> capability, IRift instance, Direction side) {
		CompoundNBT nbt = new CompoundNBT();
		
		if(instance.isRift()) {
			nbt.putBoolean("isRift", instance.isRift());
			nbt.putFloat("riftActivityPercent", instance.getRiftActivityPercent());
		}
		
		return nbt;
	}

	@Override
	public void readNBT(Capability<IRift> capability, IRift instance, Direction side, INBT nbt) {
		CompoundNBT cnbt = ((CompoundNBT)nbt);
		
		if(cnbt.getBoolean("isRift")) {
			instance.makeRift();
			instance.setRiftActivityPercent(cnbt.getFloat("riftActivityPercent"));
		}
	}
}

 

RiftCapability class:

public class RiftCapability implements IRift {
	
	private boolean isRift = false;
	private float riftActivityPercent = 0.0f;

	@Override
	public boolean isRift() {
		return isRift;
	}

	@Override
	public float getRiftActivityPercent() {
		return riftActivityPercent;
	}

	@Override
	public void setRiftActivityPercent(float riftActivityPercent) {
		if(riftActivityPercent < 0 || riftActivityPercent > 1) throw new IndexOutOfBoundsException("Rift Activity Percent cannot be less than 0 or greater than 1!");
		else this.riftActivityPercent = riftActivityPercent;
	}

	@Override
	public void makeRift() {
		this.isRift = true;
	}

	@Override
	public void closeRift() {
		this.isRift = false;
	}

	@Override
	public void riftEvent() {
		//TODO: Fire a rift event.
	}
}

 

Advice much appreciated. Thanks
